San Antonio City Council approves CPS Energy rate hike

SAN ANTONIO – With an Excessive Heat Warning in effect for San Antonio Sunday and Monday, CPS Energy is encouraging customers to voluntarily reduce their electricity use, especially during the peak hours of 2 - 7 p.m.

At this time, the Electric Reliability Council of Texas (ERCOT) says there is sufficient generation to meet state grid demand Sunday. CPS Energy has enough power to meet local energy demand as well.

Under CPS Energy’s color-coded conservation awareness notification system, Sunday and Monday are currently Yellow Days for greater San Antonio and customers are asked to conserve energy using the following tips:

  • Set thermostats two to three degrees higher from 2 – 7 p.m.; set programmable thermostats to higher temperatures when no one is home. The optimum energy-saving temperature is 78 degrees.
  • Avoid using large appliances (i.e., ovens, washing machines, etc.), especially during peak demand hours.
  • Use fans to feel 4 to 6 degrees cooler. Remember: fans cool people by moving air across the skin. They don’t cool rooms and should be turned off in empty rooms.
  • Turn off and unplug non-essential lights and appliances.
  • Close shades and blinds on windows exposed to direct sunlight.
  • Charge electric vehicles after 10 p.m.
  • Set pool pumps to run early morning or overnight; shutoff from 2 – 7 p.m.

To conserve energy at work, business customers are encouraged to:

  • Minimize the use of lighting and electric equipment as much as possible.
  • Consider shutting down or reducing non-essential production processes.

CPS Energy is in close communications with ERCOT and will provide customer and community updates as needed. If conditions change, CPS Energy will partner with the City of San Antonio, Bexar County, suburban cities and other stakeholders to help communicate any potential urgent messages. CPS Energy customers are strongly encouraged to update their contact information with the utility to stay informed of emergencies. Updates can be made online in Manage My Account or by calling CPS Energy during regular business hours at 210-353-2222.

Customers are reminded that outages can happen that are unrelated to any grid conditions. Some common causes include vehicles hitting poles and animals or balloons that may get into power lines. Community cooling centers are open for customers experiencing an outage or who may need relief from the heat.
